What is job enlargement primarily focused on?

Job enlargement is a concept in human resource management that aims to increase the variety of tasks an employee performs within their role, without necessarily increasing their level of responsibility. This approach involves adding more duties or tasks that are similar in nature and complexity to what the employee is already doing. The primary focus of job enlargement is to make the job more engaging and to prevent monotony by diversifying the tasks assigned to an employee. By incorporating a broader range of activities, it can enhance employee satisfaction and productivity.

While options relating to responsibility, motivation through rotation, and training requirements may involve important aspects of job design or management strategy, they do not accurately reflect the core essence of job enlargement itself, which is centered around increasing the quantity of similar tasks. Therefore, the correct choice accurately captures the essence of what job enlargement entails.
